Summary Introduction
To explain: The series of assays used to prove/disprove the E. coli determination.
Introduction: Escherichia coli is a gram-negative, motile, rod-shaped, enteric bacterium that is usually found in the human intestine. It is commonly found in the feces of humans, which serves as the major source of contamination of water. The presence of E. coli in sample is examined by the EMB agar plate, which serves as both selective and differential media.
